3,137,075 REGISTRY GAGE FUR BRIQUE'ITWG ROLES Ray L. Graham, Valencia, Fa, assignor tn United States Steel Corporation, a corporation of New .Iersey Filed May 4-, I962, Ser. No. 192,3% 2 Claims. (Ql. 33--l82) This invention relates to a gage for aligning the rolls of abriquetting press.

A conventional roll-type briquetting press includes a pair of power-driven spring-loaded rolls journaled on The circumferential faces of the rolls have series of mating cavities in which loose material is compacted into briquettes. Reference may be made to Burnes Patent No. 915,332, Titus Patent No. 2,729,855, or Komarek et a1. Patent No. 2,843,879 for detailed showings of presses of this type. If the cavities of the two rolls do not mate properly, the briquettes are shaped irregularly and are not sufiiciently compacted. The usual practice has been to align the rolls visually and determine whether the cavities mate only by trial and error. When abrasive materials such as iron ore are briquetted, the rolls wear rapidly and frequent replacement is necessary. The rolls of course must be re-aligned each time they are replaced; hence aligning them by trial and error leads to excessive downtime, besides tending to produce inferior briquettes.

An object of the present invention is to provide a gage which enables briquetting rolls to be aligned quickly and accurately.

A further object is to provide a gage which'includes a blade adapted to be inserted between the rolls of a briquetting press and templates fixed to the blade and adapted to be received in the briquetting cavities for aligning them.

In accomplishing these and other objects of the invention, I have provided improved details of structure, a preferred form of'which is shown in the accompanying drawing, in which:

FIGURE 1 is a top plan view of a gage constructed in accordance with my invention;

FIGURE 2 is a longitudinal section on line ILL-II of FIGURE 1; l

FIGURE 3 is a cross section on line IIIIII of FIG- URE 1; and

FIGURE 4 is a diagrammatic view of a set of briquetting rolls with my gage inserted therein. I

My gage comprises an elongated thin metal blade 1%), a handle 12 fixed to one end of the blade, a series of templates 13, l4, l and 16 fixed to one face of the blade, and another series of templates 13a, I ia, 15a and 16a fixed to the opposite face. Each template is shaped to conform with one cavity in a briquetting roll and to be received in the cavity. The templates on one face of the blade are aligned with those on the other. The distance between templates is the same as the distance 3,137,075 Patented June 16, 1964 Ice between cavities. I have shown each aligned pair of templates fastened to the blade with two rivets 17 and a machine screw 18.

FIGURE 4 shows diagrammatically a conventional briquetting press which includes a pair of rolls 20 and 20a. The surfaces of these rolls have cavities 21 and 21a. In using my gage to align these rolls, I separate the rolls sufficiently to insert blade 10 between them, and loosen the rolls with respect to their motor drive gears. I turn the rolls independently of the drive gears until the opposed pairs of templates 13 and 13a, etc. fit within cavitieszl and 21a on each side. In this manner I bring the cavities into alignment. I then fix the loosened rolls in this position and rotate them to remove the gage. I can check the alignment at any time by rotating the rolls toward each other and inserting the gage. If the rolls are properly aligned, the gage moves smoothly between them without binding. 1 rotate the rolls in reverse direction to remove the gage.

From the foregoing description it is seen that my invention affords a gage of simple construction for quickly and accurately aligning the rolls of a briquetting press. Use of the gage eliminates the guesswork inherent in the previous practice, and hence reduces the downtime as well as assuring greater accuracy.

Vfhile I have shown and described only a single embodiment of my invention, it is apparent that modifications may arise. Therefore, I do not wish to be limited to the disclosure set forth but only by the scope of the appended claims.

I claim: 2

1. A gage for aligning the rolls of a briquetting press, each of which rolls has a series of uniformly spaced briquette-forming cavities formed inits circumferential surface, said gage comprising an elongated thin metal blade, a series of spaced-apart templates fixed to one face of said blade, and a second series of spaced-apart templates fixed to the other face of said blade aligned with respective templates of the first series, each of said templates being shaped to conform with a cavity in a briquetting roll, the spacing between templates conforming with the spacing between cavities.

2. A gage for aligning the rolls of a briquetting press, each of which rolls has a series of uniformly spaced briquette-forming cavities formed in its circumferential surface, said gage comprising an elongated thin metal blade, a handle fixed to one end of said blade, a series of spaced-apart templates on one face of said blade, a second series of spaced-apart templates on the other face of said blade, fastening means fixing said templates to said blade in pairs with the templates of the second series aligned with the respective templates of the first series, each of said templates being shaped to conform with a cavity in a briquetting roll, the spacing between templates conforming with the spacing between cavities.
